Electron apps need to take the route that Eclipse used and uses. Eclipse is a resource intensive Java application (though it feels much better these days than when I first used it 12 or so years ago). One runtime, with a mechanism for installing new "views" and such. Some applications were delivered as complete Eclipse runtime downloads plus the custom additions, but usually you could just download those custom parts directly into your Eclipse runtime.

That was a reasonably effective use of a common runtime and resource.
